JoAnn I wish I were better at specific issues. It seems like a few stems every year look less than stellar here. I use Neem Oil and that seems to help any bug issues or any fungus. It seems to help a lot of things, between that mulch and epsom, that's about all I use here. I'm not a user of big chemicals.
